Salinity stress affects morpho-physiological and biochemical traits of plants. The transgenic Bt plants play a significant role in pest control, but their response and ability to cope with environmental stresses still need to be evaluated. Therefore, effect of salinity stress at 0, 50, 100, 150, and 200 mM on morphological, physiological, and molecular traits of T3 transgenic tomato plants cont...

Salinity is a major limiting factor for plant growth and development. To evaluate the impact of P5CS gene expression under in vitro salt stress condition, transgenic tobacco (Nicotiana plumbaginifolia) carrying P5CS gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mM NaCl for 28 days. Proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...

Transgenic plants and their products are being developed day by day due to their improved characteristics, and it is necessary to evaluate the safety of these plants before releasing them. Hence, the importance of the issue of biosafety of transgenic plants and the use of their products has led the regulatory agencies to create some laws called substantial equivalence. based on that, the essent...

Transformation of plants using Agrabacterium rhizogenes may affect secondary metabolite production as well as morphological changes. In this study, T-DNA from Ri plasmid in A. rhizogenes carrying pRi15834-PRT35S-GUS was introduced into tobacco leaf segments to initiate development of transformed hairy roots. Plant regeneration from transgenic roots used MS medium, and plants regenerated fro...

Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...

 Background and purpose: Transgenic rice is a type of rice that its genetic sequence has been changed to improve its quantity and quality. Bt (Bacillus thuringiensis) transgenic rice expresses Cry1Ab protein and is named Tarom Molaii. There are no studies on the effect of this type of transgenic rice on gastrointestinal health in Iran, so, this study investigated the effect of Tarom Molaii tran...

Due to population growth in the coming years, adequate food supply is the world's biggest problem, and it seems that one way to meet this need is to produce transgenic products. Transgenic products are created using modern technology to create or enhance a desirable property, such as increasing resistance to weeds or improving nutritional properties. The advantages of transgenic products includ...
